Further decompensation in cirrhosis: Results of a large multicenter cohort study supporting Baveno VII statements.

BACKGROUND AND AIMS: The prognostic weight of further decompensation in cirrhosis is still unclear. We investigated the incidence of further decompensation and its effect on mortality in patients with cirrhosis. APPROACH AND RESULTS: Multicenter cohort study. The cumulative incidence of further decompensation (development of a second event or complication of a decompensating event) was assessed using competing risks analysis in 2028 patients. A 4-state model was built: first decompensation, further decompensation, liver transplant, and death. A cause-specific Cox model was used to assess the adjusted effect of further decompensation on mortality. Sensitivity analyses were performed for patients included before or after 1999. In a mean follow-up of 43 months, 1192 patients developed further decompensation and 649 died. Corresponding 5-year cumulative incidences were 52% and 35%, respectively. The cumulative incidences of death and liver transplant after further decompensation were 55% and 9.7%, respectively. The most common further decompensating event was ascites/complications of ascites. Five-year probabilities of state occupation were 24% alive with first decompensation, 21% alive with further decompensation, 7% alive with a liver transplant, 16% dead after first decompensation without further decompensation, 31% dead after further decompensation, and <1% dead after liver transplant. The HR for death after further decompensation, adjusted for known prognostic indicators, was 1.46 (95% CI: 1.23-1.71) ( p <0.001). The significant impact of further decompensation on survival was confirmed in patients included before or after 1999. CONCLUSIONS: In cirrhosis, further decompensation occurs in ~60% of patients, significantly increases mortality, and should be considered a more advanced stage of decompensated cirrhosis.

Clinical outcomes of transjugular intrahepatic portosystemic shunt with PTFE-covered stents after liver transplantation and technical results in split and whole liver graft recipients.

OBJECTIVES: To assess the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation using PTFE-covered stents in liver transplant (LT) recipients and to analyze the technical result of TIPS creation in split grafts (SG) compared with whole liver grafts (WG). METHODS AND MATERIALS: Single-center, retrospective study, analyzing LT patients who underwent TIPS using PTFE-covered stents. Clinical and technical variables were analyzed. RESULTS: Between 2005 and 2021, TIPS was created using PTFE-covered stents in 48 LT patients at a median of 43 months (range, 0.5-192) after LT. TIPS indications were refractory ascites (RA) in 33 patients (69%), variceal bleeding (VB) in 9 patients (19%), others in 6 (12%). Ten patients (21%) received a SG. Technical success rate was 100% in both groups: in two WG recipients, (5%) a second attempt was required. An unconventional approach (combined transhepatic or transplenic access) was needed in 2 WG (5%) and 2 SG recipients (20%). Two procedure-related death occurred in the WG group. After a median follow-up of 22 months (range, 0,1-144), 16 patients (48%) in the RA group did not require post-TIPS paracentesis, in the VB group rebleeding occurred in 3 patients (33%). Fifteen patients (31%) underwent TIPS revision. Overt hepatic encephalopathy occurred in 14 patients (29%). Patient survival at 6 months, 1 year, and 3 years was 77%, 66%, and 43%, respectively. CONCLUSIONS: The feasibility and safety of TIPS creation in SG are comparable to that of WG. TIPS creation using PTFE-covered stents represents a viable option to treat portal hypertensive complications in LT recipients. KEY POINTS: • TIPS creation using PTFE-covered stents represents a viable option to treat complications of PH in LT recipients. • TIPS creation in LT SG recipients appears to be safe and feasible as in WG. • Results from this study may help to refine the management of LT patients with recurrent portal hypertensive complications encouraging physicians to consider TIPS creation as a treatment option in both SG and WG recipients.

Performance of the model for end-stage liver disease score for mortality prediction and the potential role of etiology.

BACKGROUND & AIMS: Although the discriminative ability of the model for end-stage liver disease (MELD) score is generally considered acceptable, its calibration is still unclear. In a validation study, we assessed the discriminative performance and calibration of 3 versions of the model: original MELD-TIPS, used to predict survival after transjugular intrahepatic portosystemic shunt (TIPS); classic MELD-Mayo; and MELD-UNOS, used by the United Network for Organ Sharing (UNOS). We also explored recalibrating and updating the model. METHODS: In total, 776 patients who underwent elective TIPS (TIPS cohort) and 445 unselected patients (non-TIPS cohort) were included. Three, 6 and 12-month mortality predictions were calculated by the 3 MELD versions: discrimination was assessed by c-statistics and calibration by comparing deciles of predicted and observed risks. Cox and Fine and Grey models were used for recalibration and prognostic analyses. RESULTS: In the TIPS/non-TIPS cohorts, the etiology of liver disease was viral in 402/188, alcoholic in 185/130, and non-alcoholic steatohepatitis in 65/33; mean follow-up±SD was 25±9/19±21 months; and the number of deaths at 3-6-12 months was 57-102-142/31-47-99, respectively. C-statistics ranged from 0.66 to 0.72 in TIPS and 0.66 to 0.76 in non-TIPS cohorts across prediction times and scores. A post hoc analysis revealed worse c-statistics in non-viral cirrhosis with more pronounced and significant worsening in the non-TIPS cohort. Calibration was acceptable with MELD-TIPS but largely unsatisfactory with MELD-Mayo and -UNOS whose performance improved much after recalibration. A prognostic analysis showed that age, albumin, and TIPS indication might be used to update the MELD. CONCLUSIONS: In this validation study, the performance of the MELD score was largely unsatisfactory, particularly in non-viral cirrhosis. MELD recalibration and candidate variables for an update to the MELD score are proposed. LAY SUMMARY: While the discriminative performance of the model for end-stage liver disease (MELD) score is credited to be fair to good, its calibration, the correspondence of observed to predicted mortality, is still unsettled. We found that application of 3 different versions of the MELD in 2 independent cirrhosis cohorts yielded largely imprecise mortality predictions particularly in non-viral cirrhosis. Thus, we propose a recalibration and suggest candidate variables for an update to the model.

Portal vein puncture-related complications during transjugular intrahepatic portosystemic shunt creation: Colapinto needle set vs Rösch-Uchida needle set.

Transjugular portal vein puncture is considered the riskiest step in TIPS creation with possible incidence of portal vein puncture-related complications (PVPC). The Colapinto and the Rösch-Uchida needle sets are two different needle sets currently available. To date, there have been no randomized control trials or systematic reviews which compare the incidence of PVPC when using the two different needle sets. The aim of this literature review is to assess the rate of PVPC associated with the different needle sets used in the creation of TIPS. From the described search, 1500 articles were identified and 34 met the inclusion criteria. Outcome measured was the prevalence of PVPC using the different needle sets. Overall 212 (3.6%) PVPC were reported in 5865 patients; 142 (3.5%) reported in 4000 cases using the Rösch-Uchida set and 70 (3.7%) in 1865 patients using the Colapinto set (p = 0.69). PVPC in TIPS creation are not related to the choice of needle set used in the procedure. To our knowledge, this is the first review of its kind, the results of which support the theory that while the rate of PVPC is influenced by many factors, choice of needle set does not seem to be one of them.

Hereditary hemorrhagic telangiectasia associated with cortical development malformation due to a start loss mutation in ENG.

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is a rare disorder characterized by recurrent epistaxis, telangiectasias and systemic arteriovenous malformations (AVMs). HHT is associated with mutations in genes encoding for proteins involved in endothelial homeostasis such as ENG (endoglin) and ACVRL1 (activin receptor-like kinase-1). CASE PRESENTATION: Here we describe a 22-year-old male presenting with a transient episode of slurred speech and left arm paresis. Brain MRI displayed polymicrogyria. A right-to-left shunt in absence of an atrial septum defect was noted. Chest CT revealed multiple pulmonary AVMs, likely causing paradoxical embolism manifesting as a transient ischemic attack. The heterozygous ENG variant, c.3G > A (p.Met1lle), was detected in the patient. This variant was also found in patient's mother and in his younger brother who displayed cortical dysplasia type 2. CONCLUSIONS: The detection of cortical development malformations in multiple subjects from the same pedigree may expand the phenotypic features of ENG-related HHT patients. We suggest considering HHT in young patients presenting with acute cerebral ischemic events of unknown origin.

Clinical states of cirrhosis and competing risks.

The clinical course of cirrhosis is mostly determined by the progressive increase of portal hypertension, hyperdynamic circulation, bacterial translocation and activation of systemic inflammation. Different disease states, encompassing compensated and decompensated cirrhosis and a late decompensated state, are related to the progression of these mechanisms and may be recognised by haemodynamic or clinical characteristics. While these disease states do not follow a predictable sequence, they correspond to varying mortality risk. Acute-on-chronic liver failure may occur either in decompensated or in compensated cirrhosis and is always associated with a high short-term mortality. The increasing severity of these disease states prompted the concept of clinical states of cirrhosis. A multistate approach has been considered to describe the clinical course of the disease. Such an approach requires the assessment of the probabilities of different outcomes in each state, which compete with each other to occur first and mark the transition towards a different state. This requires the use of competing risks analysis, since the traditional Kaplan-Meier analysis should only be used in two-state settings. Accounting for competing risks also has implications for prognosis and treatment efficacy research. The aim of this review is to summarise relevant clinical states and to show examples of competing risks analysis in multistate models of cirrhosis.

Transjugular Intrahepatic Portosystemic Shunts in Patients with Cirrhosis with Refractory Ascites: Comparison of Clinical Outcomes by Using 8- and 10-mm PTFE-covered Stents.

Purpose To compare the efficacy and complications of transjugular intrahepatic portosystemic shunt (TIPS) creation performed by using a 10-mm or an 8-mm-diameter polytetrafluoroethylene (PTFE)-covered stent in a consecutive series of patients with cirrhosis with refractory ascites (RA). Materials and Methods The institutional review board approved this retrospective study and informed consent was waived. One hundred seventy-one patients with RA (mean age, 58.7 years ± 10.3; 95% confidence interval [CI]: 57.2 years, 60.3 years) had undergone TIPS placement by using 10-mm (60 patients) or 8-mm (111 patients) covered stent between January 2004 and December 2012. Median follow-up time was 16.8 months (range, 3.4-84.8 months). Hemodynamic changes, incidence of hepatic encephalopathy, and long-term (>3 months) need for paracentesis after TIPS placement were evaluated and calculated by using the Kaplan-Meier method and were compared by using the log-rank test. Results Pre-TIPS demographics and clinical characteristics of the two groups were comparable. The portosystemic gradient before TIPS was 17.0 mm Hg ± 4.2 (95% CI: 15.9 mm Hg, 18.1 mm Hg) in the 10-mm group versus 16.1 mm Hg ± 3.7 (95% CI: 15.4 mm Hg, 16.8 mm Hg) in the 8-mm group (P = .164). After TIPS, the portosystemic gradient was 6.5 mm Hg ± 3.4 (95% CI: 5.7 mm Hg, 7.4 mm Hg) in the 10-mm group versus 7.5 mm Hg ± 2.6 (95% CI: 6.9 mm Hg, 7.9 mm Hg) in the 8-mm group (P = .039). The long-term need for paracentesis was greater in the 8-mm group (64 of 111 patients [58%] vs 18 of 60 patients [31%], P = .003). Overall, hepatic encephalopathy was similar in both groups (45 of 111 patients [41%] vs 26 of 60 patients [44%], P = .728). Conclusion A10-mm PTFE-covered stent leads to better control of RA secondary to portal hypertension in patients with cirrhosis, compared with an 8-mm stent, without increasing the incidence of hepatic encephalopathy. © RSNA, 2017.

Radiation doses to operators performing transjugular intrahepatic portosystemic shunt using a flat-panel detector-based system and ultrasound guidance for portal vein targeting.

OBJECTIVES: The aim of this study was to prospectively evaluate effective dose (E) of operators performing transjugular intrahepatic portosystemic shunts (TIPS) in a single centre. Patients' radiation exposure was also collected. METHODS: Between 8/2015 and 6/2016, 45 consecutive TIPS were performed in adult patients using a flat-panel detector-based system (FPDS) and real-time ultrasound guidance (USG) for portal vein targeting. Electronic personal dosimeters were used to measure radiation doses to the primary and assistant operators, anaesthesia nurse and radiographer. Patients' radiation exposure was measured with dose area product (DAP); fluoroscopy time (FT) was also collected. RESULTS: Mean E for the primary operator was 1.40 µSv (SD 2.68, median 0.42, range 0.12 - 12.18), for the assistant operator was 1.29 µSv (SD 1.79, median 0.40, range 0.10 - 4.89), for the anaesthesia nurse was 0.21 µSv (SD 0.67, median 0.10, range 0.03 - 3.99), for the radiographer was 0.42 µSv (SD 0.71, median 0.25, range 0.03 - 2.67). Mean patient DAP was 59.31 GyCm2 (SD 56.91, median 31.58, range 7.66 - 281.40); mean FT was 10.20 min (SD 7.40, median 10.40, range 3.8 - 31.8). CONCLUSION: The use of FPDS and USG for portal vein targeting allows a reasonably low E to operators performing TIPS. KEY POINTS: • The operators' E vary according to the complexity of the procedure. • FPDS and USG allow a reasonably low E to TIPS operators. • FPDS and USG have an important role in reducing the occupational exposure.

Early Liver Failure after Transjugular Intrahepatic Portosystemic Shunt in Patients with Cirrhosis with Model for End-Stage Liver Disease Score of 12 or Less: Incidence, Outcome, and Prognostic Factors.

Purpose To evaluate the incidence, outcomes, and prognostic factors of early liver failure (ELF) after transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with cirrhosis with Model for End-Stage Liver Disease (MELD) score of 12 or less. Materials and Methods Institutional review board approved this retrospective study, with waiver of written informed consent. Two-hundred sixteen consecutive patients with cirrhosis (140 men, 76 women; mean age, 55.9 years; virus-related cirrhosis, 67.6% [146 of 216 patients]) with baseline MELD score of 12 or less who underwent TIPS placement between September 1999 and July 2012 were followed until last clinical evaluation, liver transplantation, or death. The Kaplan-Meier method, log-rank test, area under the receiver operating characteristic curve, and univariate and multivariate analyses were used, as appropriate. Results Twenty of 216 patients (9.2%) developed ELF within 3 months of TIPS (10 patients died, one required liver transplantation, and nine increased the MELD score to >18). ELF was associated with lower survival, 37% versus 95% at 6 months, and 24% versus 86% at 12 months (P < .001) compared with patients without ELF. ELF occurred in 16 of 95 (16.8%) patients with refractory ascites and in four of 121 (3.3%) patients with other indications for TIPS. Multivariate analysis confirmed MELD scores of 11 or 12 (odds ratio, 3.96 [95% confidence interval: 1.07, 14.67]; P = .040), decreased hemoglobin level (odds ratio, 0.68 [95% confidence interval: 0.49, 0.95]; P = .022), and decreased platelet count (odds ratio, 0.99 [95% confidence interval: 0.99, 0.99]; P = .024) as predictors for ELF in patients with refractory ascites. Conclusion ELF is not uncommon in cirrhotic patients with a MELD score of 12 or less who undergo TIPS placement for refractory ascites (especially in patients with MELD of 11 or 12) and decreased hemoglobin level and platelet count.

Endovascular Embolization of a Large High-Flow Splenic Arteriovenous Fistula and Aneurysm Using the Amplatzer Vascular Plug II.

We describe the use of an Amplatzer Vascular Plug (AVP) II for embolizing a large high-flow splenic arteriovenous fistula and an aneurysm in a young patient. This patient presented to our center with persistent mild abdominal discomfort, 5 years after open splenectomy. Contrast-enhanced computed tomography angiography showed the presence of a fistula between the splenic arterial and splenic venous remnants and a resultant fusiform aneurysmal dilatation of the residual splenic vein. We decide to embolize the splenic artery with a 12-mm diameter AVP II with an oversizing by 70% of the vessel diameter. Celiac angiography performed 5 min postembolization revealed complete obliteration of the splenic artery and closure of the arteriovenous fistula. The overall procedure time was 40 min, and overall radiation exposure was 32 Gy cm(2) (dose-area product).

Real-time ultrasound-guided placement of a pigtail catheter in supine position for draining pleural effusion in pediatric patients who have undergone liver transplantation.

PURPOSE: Ultrasound (US) guidance is currently used for placement of wire-guided thoracic drains, and its use is associated with a decreased risk of complications. However, most studies conducted to date in this field have been performed on adult patients. The aim of this study was to report the technical success and complication rates observed during real-time US-guided placement of a thoracic pigtail catheter in pediatric liver-transplant recipients with symptomatic pleural effusion. METHODS: This was a single-center retrospective review of the clinical records and images from pediatric liver-transplant patients with symptomatic pleural effusion who had undergone real-time US-guided pleural-space puncture followed by placement (via the Seldinger technique) of a pigtail catheter for drainage, between May 2006 and June 2014. RESULTS: We identified 25 patients who had undergone 41 pigtail catheter-placement procedures during the study period. The patients' mean age (± SD) was 4.2 ± 3.9 years (range, 2 months to 16 years), and their mean weight was 14.2 ± 7.2 kg (range, 4.5-33 kg). Seventeen procedures had been performed in the intensive care unit, and 8, in patients undergoing mechanical ventilation. Twelve of the 41 procedures had been performed in patients with altered hemostasis (ie, platelet count < 50 × 10(3) /µl and/or international normalized ratio > 1.5). The size of the pigtail catheters ranged from 5 F to 8.5 F. The technical success rate was 100%, with no major complications such as pneumothorax or hemothorax. Accidental dislocation of the catheter occurred in four patients (9%) over 3-10 days after the first procedure. CONCLUSIONS: In our experience, real-time US-guided pleural-space puncture, performed at bedside, with the patient in the supine position, followed by placement of a pigtail catheter for drainage of effusion, is safe to use and has a high rate of technical success in pediatric patients. © 2015 Wiley Periodicals, Inc.

Simply red? The effects of distinct colours and sustainable production methods on the consumers' preferences for healthier sweet peppers.

The purpose of this paper is to thoroughly assess the value of colours in consumers' preferences for sweet peppers, and the association with more sustainable methods of production in the consumers' minds. Furthermore, this study provides novel insights into the influence of colours on the willingness to pay (WTP) for vegetables. It explores the interplay between colours, food attributes, and socio-demographic characteristics among consumers, marking the first attempt to examine this relationship comprehensively. A discrete choice experiment, based on consumers' preferences for sweet pepper attributes (price, colour, and production method), was implemented and a Seemingly Unrelated Regression model was then applied to evaluate the willingness to pay for different colours. The study has revealed that different colours provide consumers with different utilities and WTP in the choices of potential healthier foods. In addition, gender, age, education and number of family components play a role in affecting consumers' WTP of food linked to colour. Finally, it was found that consumers' knowledge for certain pepper colours with different antioxidant contents is interrelated. This study introduces several novelties, in particular a positive correlation between interest in antioxidants and colours was found, suggesting that interest in healthy food properties might move consumers towards a specific sensory choice.

The interplay of food-related lifestyle and eating behavior in Italian women.

Introduction: Women play a crucial role in food shopping and preparation, and their food choices have significant implications for their health and that of their families. This study aims to provide a perspective on women's eating lifestyle, which has undergone significant changes. Methods: A factor analysis was conducted to assess the degree of involvement in food choices and the types of food items consumed among a sample of 399 Italian women. Results: Through cluster analysis, four segments were identified: hedonic food consumers, sustainable- and balanced-diet consumers, food experimenters, and no food fondness consumers. The results reveal a correlation between the degree of food involvement and the type of food consumed. Discussion: Furthermore, the food lifestyle of the sample is partially dependent on age. Individuals aged 25-28 years show more hedonic food consumption behavior, while the older age group (44-64 years) falls into the sustainable and balanced diet consumer cluster (the largest cluster) and the cluster of those who do not express definable food choices (no food fondness).

Plastic-free behavior of millennials: An application of the theory of planned behavior on drinking choices.

This study explores the factors that influence millennials' intentions and behavior regarding reduced plastic consumption. An extended theory of planned behavior was established as a conceptual model that explicitly analyzed both the role of past and stated behaviors. The stated behavior was measured using a projective technique. The data obtained from a survey of 741 Italian respondents were analyzed through multiple correspondence analysis and partial least squares structural equation modeling. The results of the projective technique characterized "plastic-free" behavior as a unidimensional construct. Structural equation modeling showed that attitudes, subjective norms, and perceived behavioral control influence the intention of millennial consumers to reduce the use of plastic drinking bottles. The perceived behavioral control is the strongest predictor of intention (ß = 0.304; p < 0.001), followed by social norms (ß = 0.271; p < 0.001) and attitudes (ß = 0.130; p < 0.001). The past behavior construct positively and significantly affects attitude (ß = 0.165; p < 0.001), intention (ß = 0.231; p < 0.001), and stated behavior (ß = 0.073; p < 0.05) constructs. The latter is also positively predicted by intention (ß = 0.151; p < 0.001). Based on the results, actions and incentives for reducing plastic consumption were provided.

Consumers' Attitudes and Purchase Intention for a Vitamin-Enriched Extra Virgin Olive Oil.

This study aims to examine Italian consumer preferences for extra virgin olive oil (EVOO) enriched with vitamins and to analyze the key drivers that affect consumer choices for this product. Specifically, we assessed consumers' intention to purchase the enriched product compared to the conventional one. The methodology adopted inferential and multivariate statistical techniques: (1) exploratory factor analysis (EFA), (2) ordinary least squares regression (OLS) and (3) non-hierarchical clustering. This study appears to be the first research project related to exploring consumers' interest in an extra virgin olive oil enhanced with vitamins, thereby providing preliminary indications. The main results represent a significant starting point for the development of new marketing strategies for the food industry.

Development of a Novel Clinical and Radiologic Risk Score to Predict Septic Complications After Urinary Decompression in Patients with Obstructive Uropathy.

Background: Well-defined clinical predictors of sepsis after upper tract drainage for obstructive uropathy are lacking. The study aim is to develop a data-driven score to predict risk of sepsis after decompression of the upper urinary tract. Materials and Methods: Complete clinical and radiologic data from 271 patients entering the emergency department for obstructive uropathy and submitted to stent/nephrostomy tube decompression were evaluated. The Charlson Comorbidity Index (CCI) was used to score comorbidities. The definition of sepsis was an increase in ≥2 Sequential Organ Failure Assessment points (or a postoperative persistently elevated score +1 additional increase) and documented blood or urine cultures. Descriptive statistics and stepwise multivariable logistic regression modeling with receiver operating characteristic analysis were performed to obtain a composite risk score to predict the risk of sepsis after surgery. This study was approved by our local Ethics Commitee (Prot. 25508). Results: Fifty-five (20.3%) patients developed sepsis. At multivariable analysis, CCI ≥2 (odds ratio [OR] 3.10; 95% confidence interval [CI] 1.36-7.04), maximum body temperature ≥38°C (OR 4.35; 95% CI 1.89-9.44), grade III-IV hydronephrosis (OR 2.37; 95% CI 1.10-4.98), HU of the dilated collecting system ≥7.0 (OR 4.47; 95% CI 2.03-9.81), white blood cells ≥15 × 103/mmc (OR 2.77; 95% CI 1.24-6.19), and C-reactive protein ≥10 (OR 3.27; 95% CI 1.41-7.56) were independently associated with sepsis. The positive predictive value of a true sepsis increased incrementally as a function of number of positive variables, ranging from 1.6% to 100.0% among patients with 1 and 6 positive variables, respectively. Conclusion: Our risk score identifies accurately patients with an increased risk of sepsis after urinary decompression for obstructive uropathy, hence improving clinical management.

Cost-effectiveness analysis of personalised versus standard dosimetry for selective internal radiation therapy with TheraSphere in patients with hepatocellular carcinoma.

Aims: To perform a cost-effectiveness analysis (CEA) comparing personalised dosimetry with standard dosimetry in the context of selective internal radiation therapy (SIRT) with TheraSphere for the management of adult patients with locally advanced hepatocellular carcinoma (HCC) from the Italian Healthcare Service perspective. Materials and methods: A partition survival model was developed to project costs and the quality-adjusted life years (QALYs) over a lifetime horizon. Clinical inputs were retrieved from a published randomised controlled trial. Health resource utilisation inputs were extracted from the questionnaires administered to clinicians in three oncology centres in Italy, respectively. Cost parameters were based on Italian official tariffs. Results: Over a lifetime horizon, the model estimated the average QALYs of 1.292 and 0.578, respectively, for patients undergoing personalised and standard dosimetry approaches. The estimated mean costs per patient were €23,487 and €19,877, respectively. The incremental cost-utility ratio (ICUR) of personalised versus standard dosimetry approaches was €5,056/QALY. Conclusions: Personalised dosimetry may be considered a cost-effective option compared to standard dosimetry for patients undergoing SIRT for HCC in Italy. These findings provide evidence for clinicians and payers on the value of personalised dosimetry as a treatment option for patients with HCC.

Serum bilirubin and platelet count: a simple predictive model for survival in patients with refractory ascites treated by TIPS.

BACKGROUND & AIMS: Refractory ascites in patients with cirrhosis is associated with poor survival. TIPS is more effective than paracentesis for the prevention of recurrence of ascites but increases the risk of encephalopathy while survival remains unchanged. A more accurate selection of the patients might improve these results. The aim of the present study was to identify parameters of prognostic value for survival in patients with refractory ascites treated with TIPS. METHODS: One hundred and five consecutive French patients with cirrhosis and refractory ascites treated with TIPS were used to assess parameters associated with 1-year survival. The model was then tested in two different cohorts: a local and prospective one including 40 patients from Toulouse, France, and an external one including 48 patients from Barcelona, Spain. RESULTS: The actuarial rate of survival in the first 105 patients was 60% at 1 year. Using multivariate analysis, only lower bilirubin levels and higher platelet counts were independently associated with survival. The actuarial 1-year survival rate in patients with both a platelet count above 75×10(9)/L and a bilirubin level lower than 50 µmol/L [3mg/dl] was 73.1% as compared to 31.2%, in patients with a platelet count below 75×10(9)/L or a bilirubin level higher than 50 µmol/L. These results were confirmed in the two different validation cohorts. CONCLUSIONS: The combination of a bilirubin level below 50 µmol/L and a platelet count above 75×10(9)/L is predictive of survival in patients with refractory ascites treated with TIPS. This simple score could be used at bedside to help choose the best therapeutic options.

Management of upper retropharyngeal abscesses in children: Two case reports of a troublesome situation.

Management of upper retropharyngeal abscesses in children is challenging. In surgical cases, ultrasound-assisted intra-operative procedures may be helpful to reach peculiar locations, thus reducing surgical morbidity and complications rate.
